oARamcE r ts-.1 G. Haupt i Application Janua y This invention relates known as bicycles More particularly, the invention deals with vehicles ofthis class, wherein the bicycleframe is formed of-a seat wheel section and a handle bar wheel section, the sections being detachably coupled, whereby the seat wheel section is adapted for attachment to an adaptor coupling on a baby.carriage and, whereby the baby carriage may be propelled through the drive mechanism of the seat wheel section. The novel features of the invention will be best understood from the following descripttion,:when taken together with the accompanying drawing, in which certain embodiments of "meinvennonare 'disclosed and, in which, the separate parts are designated by suitable reference characters in each of the views and, in which;

Fig. 3 is aface view of the-unitshown-in Fig. 2 looking from left to right or Fig. 2, andindicate tv h ar ie aala Fig. 4 is a side view of the in Fig. 3. V s

Fig. 5 is a diagrammatic side view showing the two parts or sections of the bicycle in assembled relationship; and

Fig. 6 is a longitudinal sectional view through the coupling employed between the seat or drive structure k as shown to whatare generally section and the front wheel or carriage sections.

Considering Fig. 5 of the drawing, Ill represents a drive or seat section of a bicycle comprising a suitable frame H, a seat l2, wheel l3, sprocket and chain drive It actuated through crank pedals [5, :as in the usual structures of vehicles of this type and kind.

The frame H has a short lower extension IS, the end of which has a section removed to form a projecting key member H. To the end portion l6 and extending beyond the key member I1 is welded or otherwise secured a coupling sleeve l8. The sleeve l8 forms a. socket l9 for the reception of a rod 20 having, at its free end, a projecting key member 2!, cooperating with the key ll to maintain the parts against relative rotation one upon the other. The coupling sleeve l8 has a suitable winged or other set screw 22 to retain the parts in coupled relationship. It will be apparent that the key members l1 and 2| comprise half sections of rods or tubes, from which the vehicle or the adaptor unit of a vehicle is constructed.

man, N ew York,'N. Y. Q r 5, 1946, Serial No. 641,239 i aims m-2 y The showing in Fig. 6 of the drawing is applicable 'to theshowing of the. vehicle combinations as in Figsl and 5, thus, in Fig. 5, the frame part 28 corresponds to the part 20 of Fig. 6 and, in Fig. l, thepart 20 corresponds to. the part 20 of Fig. 6. The part 20' comprises anextension on thefront frame 23 of a bicycle, in which is mounted the front wheel 24 andhandle bars 25 in accordancewith conventional practice in bicycle construction. *As'm'y' invention is not concerned with the specific structure of the bicycle or its parts aside from the detachable coupling between the parts: or sections; n-o detail description :thereof is herein given.

, In Fig. 1 of thedrawing I have shown diagrammatically at 26 .a'babycar-riage having pairs of front wheels 21; and rear wheels 28-only one of the wheels 28 being shown in dotted lines in Said figure. It is readily understood I that conventionaldcharacters of the type shown have pairs of frontv andzrear :wheels and'the. rear wheels are omitted to simplify thepshowing. At 29 is 'shown-thehandle. of theacarriagewhich, in the assemblage with the rear section In of the bicycle,

as ;shown,; forms. the handlebars: otthe vehicle combination disclosed. At 30 is shown the rear axle of the baby carriage 26. To this axle is fixedly or otherwise secured an elongated block 3|, note Fig. 4. The block 3| has a longitudinal channel 3| for receiving the axle 3|].

The block 3| has centrally thereof a vertical bore 32, in which is mounted a downwardly directed shaft or trunnion .33 of a fork-shaped coupling 34. Between the cross-head of the coupling 34 and the block 31 and around the shaft 33 is a suitable ball bearing 35. A split ring 36 is mounted on the shaft 33 below the block 3| to hold the parts 3|, 34 in assembled relationship, the ring 36 seating in a groove 31 in the shaft 33.

The block 3|, including the coupling 34, constitutes part of an adaptor unit .for coupling the baby carriage with the drive section 10 of the bicycle. The remainder of this unit comprises the rod 20", including the enlarged head 38 at its end pivotally secured in the fork-shaped coupling by a pivot pin 39.

It will be apparent that the adaptor unit forms what might be termed a unitable coupling of the drive section of the bicycle with the baby carriage axle so that, as the baby carriage is propelled by the drive section, the carriage 26 may be tilted to raise the front wheels 21 off from the ground and, at the same time, the carriage may be swung on the vehicle axle 33 in directingthe tandem combination of carriage and bicycle in any direction over a roadway.

From the foregoing, it will be apparent that the combination vehicles disclosed may be interchanged from time to time, so as to provide a two-wheel bicycle usable as such and a bicycle propelled baby carriage. In other words, after the baby carriage has served its. purpose and function, the bicycle becomes usable at all times as an ordinary bicycle. It will thus be apparent that, in merchandising the combination vehicle, the bicycle will be constructed of the front and rear sections detachably coupled one with .respect J to the other and with this combination will'be sold the adaptor unit, or this unit may bepurchased at any desirable time and all that will be necessary to do is to attach or mount the adapter unit on the baby carriage. On the other hand,

the carriage may be constructed with an adaptor" or coupling as a part thereof, depending entirely upon the merchandising program selected. In other words, the vehicle combination as disclosed in Fig. 1 may be sold as such and, together with this sale, the front wheel unit may also be purchased or the front wheel unit acquired at any other time. 7

In most instances, a baby carriage has a limited period use in the average home and, from this standpoint, the drive'or propelling section of the carriage combination can be converted into a bicycle usable by the infant at a mature date. 'Having fully described'my invention, what I claim as new and desire to secure by Letters Patent is: 1

1. The combination with a baby carriage, of an adaptor coupling attached to part of the carriage frame adjacent one pair of wheels of the carriage frame, means at one end of said coupling forming a universal mounting on the carriage frame, a drive wheel and seat section having a 40 coupling socket, and the other 'end of said adaptor coupling and the coupiing socket having interengaging means keying-and retaining the adaptor coupling with said drive wheel and seat section.

2. The combination with a. baby carriage, of a 45 seat frame, a. drive wheel in the seat frame, manually actuated means in the seat frame and actuating said drive wheel in propelling the carriage over a surface, the frame adjacent said drive wheel having a coupling socket, an adaptor unit, means at one end of said unit attached to the carriage providing swinging and tilting of the carriage with respect to the seatfrarne, and the other end of said unit having means engaging the coupling socket to retain the adaptor unit against rotation and detachment with respect to the seat frame.

3. In a combination baby carriage and seat and drive frame, an adaptor unit for coupling the carriage with the seat and drive frame, said unit comprising a red, one end of which is fashioned to form a coupling with the seat and drive frame, the other end of the rod terminating in an enlarged cross-head, a fork-shaped couplin pivoted to the ends of said cross-head, said coupling having a downwardly extending trunnion centrally thereof forming a pivot axis, an elongated block in which said trunnion is mounted for rotation thereby providing rotary movement of the coupling in said block and swinging movement of the cross-head in said coupling in providing a universal mounting at said end of the adaptor unit rod, and said block having means for engaging apart of the carriage frame.
